Abstract: A simple microsynthesis of 3-substituted rhodanines starting from the isothiocyanates (alkyl, aralkyl, and aryl ITC) and thioglycolate via addition reaction and subsequent cyclization of thus formed N-substituted thiocarbamoylmercaptoacetates is described. Differences in u.v. spectra of prepared substances and in reactivity of aryl and aralkyl ITC with thiogly colate to give cyclization products are discussed in connection with the nature of the substituent. Also a chromatographic separation of 3-substituted rhodanines and their intermediates is described.
